We build the sending infrastructure, write sequences that speak to CTOs and heads of product rather than to everyone, and run the campaigns through to a booked demo.
Illustrative dashboard. Yours reports on your own sends.
Two things kill it, and only one of them is the copy. The first is that the mail never arrives. The second is that when it does arrive, it reads like it could have been sent to anyone.
Deliverability stopped being a dark art in February 2024, when Google and Yahoo published enforceable requirements for bulk senders, followed by Microsoft in 2025. If you send at volume you now need SPF, DKIM and DMARC aligned on the sending domain, one-click unsubscribe under RFC 8058 honoured within two days, and a spam complaint rate held below 0.30%, with 0.10% the level worth actually targeting. Miss those and mail is rejected outright with a 550 error. It does not quietly land in a spam folder where you might eventually notice it.
Speed of reply matters as much as the reply itself. Harvard Business Review research by Oldroyd, McElheran and Elkington found companies that contacted a web lead within an hour were about seven times more likely to have a meaningful conversation with a decision maker than those that waited just one hour longer, and more than sixty times more likely than those that waited a day. In the same study only 37% of firms managed to respond within an hour. Outbound has the same physics: a warm reply that sits for two days is a cold lead again.
So we build both halves. Dedicated email infrastructure separate from your product and billing mail, then sequences written around the specific problem your software removes. It sits alongside our wider cold email campaigns and B2B lead generation work. Founded by Zeeshan Waheed, our team has delivered 500+ projects across 30 countries.
Sender requirements are from Google, Yahoo and Microsoft published guidance. The response-time research is Harvard Business Review, March 2011. Neither figure is a claim about our results.
The order matters. Most failed SaaS outbound sends real volume before the sending reputation exists to carry it.
Illustrative flow. Wired into your own system.
An outbound engine, not a list and a hope.
Private domains and inboxes that carry only your reputation, kept entirely separate from the domain your product notifications and invoices go out on.
Your reputation onlySPF, DKIM and DMARC aligned, one-click unsubscribe under RFC 8058, and complaint monitoring against the 0.30% ceiling that triggers rejections.
Passes bulk sender rulesFirmographic and technographic targeting down to the stack a company runs, so the message can reference something real rather than a merge field.
Lists worth sending toFive to seven touches that change angle rather than repeat, written around integration risk, migration cost and the metric the buyer is actually measured on.
Written for engineersPositive replies worked while they are still warm, objections answered, and the demo booked into your calendar rather than left in an inbox overnight.
Replies worked same dayInbox placement, reply rate, meeting rate and pipeline by sequence, so you can see which angle is working instead of which month was busy.
See what is workingNamed by vertical rather than by client, because most of this work is under NDA.
A Series A project management platform had no outbound function. We built the infrastructure, wrote sequences aimed at engineering managers, and launched inside 14 days. Outbound is now their primary growth channel.
A developer tools startup was running generic templates at a 2% reply rate. We rebuilt the messaging around engineering pain points and stood up dedicated infrastructure, taking replies to 12% and scaling to 80 demos a month.
An HR tech platform needed a predictable channel beyond inbound. Multi-touch sequences aimed at HR directors and CHROs generated $1.2M in new ARR in the first year.
Client results from our own engagements. Outcomes depend on offer, market and list quality, so treat these as what has been achieved rather than what is promised.
The maths works when the deal is worth chasing and the buyer is findable.
You have a repeatable pitch and someone to take the calls, but demand generation is entirely inbound and therefore entirely out of your control.
Add a channel you ownThe founder is still the best closer and the worst prospector. Outbound fills the calendar so the founder only does the part that needs them.
Protect founder timeA narrow ICP is a gift to outbound. When you know exactly which 4,000 companies matter, list quality stops being the bottleneck.
Narrow beats broadWhen a customer is worth five or six figures a year, a handful of extra demos a month changes the forecast rather than the dashboard.
Few deals, big impactSame product, new market, no brand recognition and no inbound yet. Outbound is usually the only channel available on day one.
Enter cold marketsYou have runway and a number to hit. Outbound is the channel that can be stood up in weeks rather than quarters.
Live in about 14 daysInfrastructure is a one-off build. Running campaigns month to month is the retainer.
Infrastructure, sequences and lists, built and handed over.
We run the campaigns, work the replies and keep deliverability healthy.
Several products, regions or brands to run in parallel.
Sending tools, data and CRM seats are billed by those vendors directly, so you keep the accounts and the margin. We size the exact scope on the call before quoting.

imisofts builds and runs it end to end for B2B SaaS: dedicated sending domains and inboxes, SPF, DKIM and DMARC authentication, controlled warm-up, ICP research and list building, multi-touch sequences written for technical buyers, and reply handling through to a booked demo. Founded by Zeeshan Waheed, the team has delivered 500+ projects across 30 countries and is normally sending in about 14 days. Book a call at https://cal.com/zeeshanwaheed/30min.
It depends on your ICP size, your average contract value and your offer, so any agency quoting you a number before seeing your market is guessing. What we can commit to is the input: authenticated infrastructure, verified lists, sequences written for your buyer, and replies worked the same day. Our SaaS clients have ranged from a handful of high-value demos a month to 80. We size a realistic range with you on the audit call using your own numbers.
Because a spam run on your primary domain damages the reputation that carries your invoices, password resets and product notifications. Once that domain is in trouble, business-critical mail starts failing. We always send from separate domains so the worst case is a disposable sending domain rather than your company's ability to email customers.
For bulk senders: SPF and DKIM in place with DMARC aligned on the sending domain, one-click unsubscribe implemented per RFC 8058 and honoured within two days, and spam complaint rates kept below 0.30%, with 0.10% the level worth targeting. Google and Yahoo began enforcing in February 2024 and Microsoft followed for high-volume senders in 2025. Non-compliant mail is rejected with a permanent 550 error rather than delivered to spam.
About 14 days. Domains and inboxes are provisioned and authenticated in the first 48 hours, then warm-up runs for roughly two weeks to build sending reputation before any real volume goes out. Skipping the warm-up is the single most common reason a new outbound programme never recovers.
In the United States, CAN-SPAM allows B2B cold email with accurate headers, a clear physical address and a working opt-out honoured promptly. The EU, UK and Canada are stricter, with CASL in particular requiring a lawful basis for each contact. We set up suppression, opt-out handling and record-keeping to match the markets you sell into, and we are not your lawyers, so confirm your own position before scaling.
We check where your mail is actually landing, whether your domains are authenticated correctly, how your sequences read to a technical buyer, and what a realistic demo range looks like for your ICP.
